MECHANISNI FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 612,442, dated October 18, 1898.

Application led J' illy-10, 1896.

To all whom it may concern:

Be it known that I, FRED C. THOMPSON, of Burton, in the county of King and State of Washington, have invented a new and useful Improvement in Mechanism for Converting Motion, of which the following is a full, clear, and exact description.

This invention is an apparatus by which movement may be transmitted between two rotary shafts through the medium of intervening reciprocal rods; and the invention also comprises means by which the movement of rotary shaft.

This specification is the disclosure of one form of my invention, while the claims deiine the actual scope of the invention.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the portion of the invention by which movement is transmitted from the rotary shaft to the reciprocal rods. Fig. 2 is a vertical section of the same.- Fig. 3 is. a side elevation of the mechanism for transmitting the movement of the reciprocal rods to the rotary shaft, and Fig. 4 is a plan View thereof.

The invention is particularly adapted to windmills, and in the drawings is shown in this connection. The tower A carries a head C, which has a downwardly-extending neck 13, mounted with ball-bearings 12 upon the topof the tower. Revolubly mounted within the head C is a shaft 14, which carries the wind-wheel and which may be drivenV thereby through the medium of any suitable or desired devices. Mounted in the tower A is an inner pump-rod 37 and an outer tubular pumprod 36, the two rods being reciprocal independently and the rod 37 having a joint 40, permitting the upper portion of the rod to turn independently of the lower portion, and the rod 36 having a joint 38, also permitting the upper portion of the rod to turn independently of the lower portion. This turning of the upper portions of the rods 36 and 37 is in unison with the turning of the head C on the bearings 12, which it will be understood is brought about by the adjustment of the windwheel. (Not shown.) This adjustment of Serial No. 598,714. (No model.)

the wind-wheel is eifected by the vane 48, that is attached to thehead C.

The shaft 14 is provided with two double cranks, (respectively designated 15 and 16.) To these cranks the links 46 and 47 are respectively pivoted. The links 46 and 47 are ,respectively pivoted to the pins 43a and 45, carried, respectively, on the rods 36 and 37. Also pivoted to the pins 43a and 45 are links 43 and 44, the remaining ends of which are pivoted to a bracket 42, standing on the head C. As the shaft 14 is revolved under the inuence of the wind-wheel the links 46 and 47 transmit reciprocal movement to the rods 36 and 37 and cause the same to reciprocate oppositely the one within the other.

The device for transmitting the reciprocal movement of the rods 36 and 37 into rotary movement is shown in Figs. 3 and 4. This consists of a power-shaft 49, revolubly mounted at a suitable point in the tower A. Fixed to the shaft 49 is a wheel 57, with which clutches h and 56h, respectively, engage. The clutches 55b and 56b are respectively carried on disks 55 and 5G, that are loose on the shaft 49. Eccentric pinions 55 and 56 are carried Xedly by the disks 55 and 56a and are loose on the shaft 49. These pinions mesh with eccentric internal sectors 54, respectivley carried on frames 51 and 52, which swing on a pivotal shaft 50. The sectors 54 respectively have arms 58 and `59 in connection, respectively, with the rods 36 and 37. The reciprocation of the rods 36 and 37 causes the eccentric sectors 54 to be moved oppositely on the pivot 50. This imparts a rolling move ment to the eccentric pinions 55 and 56, which also drives the disks 55a and 56, and through the medium of the clutches 55b and 56b the wheel 57 is continuously driven, and the shaft 49 is driven through the medium of the wheel 57. Power for any purpose may be taken from the shaft 49.

Theinvention is useful in connections other than that shown, but, as will be understood, is particularly adapted to windmills.

Having thus described `my invention, I claim as new and desire to secure by Letters Patent-1- 1. The combination, with the rods of a windmill, held to slide one in the other, a driving-x shaft having oppositely-disposed crank-arms,

and link connections between the said arms and the said rods, of a power-shaft, segments having toothed surfaces eccentric to the power-shaft, which'shaft passes through the said segments, and a connection between each segment and one of the said rods, pinions eccentrically mounted on the power-shaft and engaging with the teeth of the segments, disks secured to the said pinions, a pulley secured on the power-shaft between the said disks, and clutch-arms oppositely disposed and pivotally connected one to each disk, the said arms being spring-controlled and adapted for engagement with the peripheral surface of the pulley at opposite sides, as and for the purpose specifled.

2. The combination of a shaft, awheel fixed to the shaft, two disks loose on vthe shaft and arranged one on each side of the wheel, a clutch carried by each disk, the clutches respectively engaging the wheel and imparting movement to the wheel when the disks move each in a certain direction, a gear-Wheel in connection with each disk, and two sectors swinging independently on a common axis and respectively engaging the gear-wheels, said sectors being capableof oscillatin g movement in a plane transverse to the shaft whereby to continuously drive the shaft and independently reciprocal rods connected respectively with the sectors to swing the same.

3. The combination of two independent reciprocal rods, an independent sector connected with and driven by each rod, a shaft, a wheel fixed to the shaft, two gears loose on the shaft and respectively ineshed with and driven by the sectors and a clutch carried by each gear, the clutches being respectively engaged with the wheel to impart movement thereto.
